CROSSING GATE.

Application Ied May 23,

rlhis invention relates to gates or barriers for a railroad, railway and other crossings.

rlhe principal object of the invention is the provision of improvements in the construction and operation of gates and barriers ot the indicated character, hereinafter fully described and illustrated in the accompanying drawings, in Which-` ligure 1 is one. of the .gate units, at one of the approaches to thel railroad, the gates being shown in the closed or obstructin positions.

.li`i 2 is a view similar to Fig. 1, but showF ing the in the open or noirobstructing positions.-

Fig. 7. is a sectional view taken on the line 7M? of Fig. 1.

l? ig. 8 is a side elevation oi' a modified :form of the invention, and shown partly in section.

'.lhe features of the invention shown in liigs. 1 to 7 inclusive of the drawings are` applied in conjunction with a railroad and a crossing, by Way of example. ln accordance therewith it is to be understood that use will be made of two similar units respectively arranged at the crossing approaches to the railroad tracks on opposite sides with respect thereto so as to be operated by a train service member to close the gates which Will reniainclosed While the train is passing, and gates after the train has passed the crossing. v

:inasmuch as each unit at each crossing approach will be similar in construction and operation, a description of the construction and operation of one of the units Will suffice ior both. The unit includes a fixed frame structure 10 built to the Width of the crossing and suiiiciently large to allow vehicles to pass therethrough. The said structure 10 comprises vertical side members 11, a central vertical member 12 and top horizontal members 13 Which are connected together, and which are also connected With the upper ends et `the vertical members 11 and 12. The lower ends of the members 11 and 12 are firmly anchored in the ground. Tiltable 19528.` Serial No. 280,052.

supports 14` are arranged near the top of the frame structure 10. each of said supports 14 being tiltable by being pivotally connected at one end as at 15 to a portion of the iframe structure 10. llldeans is arranged on the frame structure 10 which `is operable to impart tilt- .ing movement to each of the supports 14. The said means includes a disk crank 16 supported for operation by a bearing 17 attached to the horizontal members 13. band 18 loosely surrounds the circum'lerential edge of the disk of the crank. The end et each of tle supports 1 4 remote from the pivotcd end, is connected with a toggle joint 19, and the latter is connected Wit-l1 the band 18. Arranged to travel on each ot the tilta-ble supports 14 into and out of' a closed or obstructing' position is a gate 20. The gate 2O is provided With a carrier or hanger 21, pivotally connected as at 22 in order that tllecarrier or hanger may tilt or rock. T he carrier 21 is provided with rollers 23 which roll iu contact with the support 14. A dependingl lug 24 is arranged on each end olE the carrier 21. The frame structure 10 is provided with spring buffers or stops 25, there being one buffer or stop 25 on each of the outermost side members 11, and tivo respectively on opposite sides of the central vertical naine ber 12. Each of the outermost side members 12 presents an abutment indicated at 2G, and the centralvertical member 12 also presents an abutment indicated at 27. .lt will be understood that when each gate 2O moved to the closed or obstructing position, one of the lugs 24 Will encounter one ol the laitiers er stops 25 on the vertical member 1.2 and be cushioned thereby, .andwvill be limited in its movement by contact with the abutment 2i' to the closed or obstructing position. lt will also be apparent that when each gate moves to the opened or non-obstructing position, the other lug 24 Will `encounter the buiier or stop 25 on the related member 11, thereby cushioning the same, the gate being limited in its movement to the opened or non-obstructing position by the abutment 26.

It Will be apparent that When each support 14 is tilted to one position that its gate 2O Willtravel on the support 14 to a closed or obstructing position as shown in Fig. 1, and that When said support 14 is tilted to its other position, the gate 20 Will travel on the support 14 to the opened or non-obstructing position, as shown in Fig. 2. The means hereinbefore referred to which serves for the purpose of tiltingthe supports 14 is operated y a means presently to be described. The disk crank 16 has connected therewith an arm 28. A length of cable 29 is connected with the Varm 28 as at 30. The cable 29 is guidedfor movementby. sheaves 31 some of which are arranged on the frame structure 10, and others are operatively positioned in the road bed. Each end of the cable 29 is pivotally connected as at 32 with a track obstacle 33 secured to a rock shaft v34 supported by suitable bearings 35 attached to two of the railroad ties. Each ot the obstacles 33 is positioned to be encountered by a train service member '.(not shown). The service member Y encounters one of the obstacles 33 which er;-

er-ts a pull -on the cable 29, which in turn exerts a pull on the arm 2S, causing the disk crank 16 to operate, and as a consequence the tilt-able supports 14 will be moved to incline downwardly and inwardly toward the center of the trame structurelO. The gates 2O will then ride or travel on the supports 14 to the closed or obstructed positions as shown in FiO. 1. l/Vhen the cable 29 is pulled 'for the purpose of moving the gates to the closed or `obstructing positions, the other obstacle 33 connected vwith the cable 29fwill be brought to a position to be encountered by the train service-member, after passing the crossing. This will result in a reverse operation o1 the disk crank 16, and the tilting of the supports 14 to positions allowing the gates 20 to travel or ride on the supports 14 to the opened or non-obstructing positions. Y

The closing of the gates 2O is accompanied by theA sounding of an alarm in the-form of a bell 36 attached to a portion of the Aframe structure 10, the said bell 36 being operated by a cable 37 or other ieXible member. A portion of the cable 37 is wrapped around a rotor 38 forming a part of the bellV 36, and which produces the ringing sound, and each of the ends of the cable 37 is connected with the carrier 21 of one of the gates, as at 39. The cable 37 is guided for movement by small sheaves 40 on portions of the frame structure 10.

In Fig. 8 of the drawing there is shown a modified Vform of the invention. In this form of the invention there is provided a barrier 41 provided with a shaft 42 journaled in a bearing 43 for the purpose of mounting the barrier 41 for pivotal movement. One end of the barrier 41 basa weight 44 which serves for moving the barrier 41 to a normal nonobstructing position. A spool 45 is 'fast on the shaft 42. One end of a piece of cable 46 isV connected with the spool 45. the oppo, site end is connected with a spring 47, and the spring is connected with a band 48 looselv surrounding the disk ol; a disk crank 4t).

The disk crank 49 has connected therewith an;

arm 50 which is pivotally connected as at 51 with a. guide cable F2. Movement of the cable 52 in one direction operates the disk crank 49 to exert a pull on the cable 46 bringing the barrier 41 to the obstructing position. 1When the cable 52 is moved in an opposite direction, the barrier is free to move to the normal position under the inuenee of the weight 44, which causes the cable 46 to be wrapped on the spool45 ready to be pulled to again bring the barrier 41 to the obstructing position.
